The efficient formulation of layered gels that encompass both hydrophilic and hydrophobic domains could lead to novel materials with a range of vital functionalities. To facilitate the fabrication of these materials, we perform dissipative particle dynamics (DPD) simulations to model the formation of two-layered stackable gels where the gels are incompatible and their respective solvents are immiscible...
Organic semiconducting/ferroelectric blend films attracted much attention due to their cross-talk-free resistive property. Blend films were fabricated from the co-dissolved solution of both semiconducting and ferroelectric components. Spinodal decomposition induced phase separation which was the key structure for determination of resistive property in such blend films. However, till now only seldom...
While there is a growing body of work that supports the self-assemblies of nanotubes and nanorods, little attention has been devoted to understand the relation between their length and the kinetics of self-assembly in polymer composites. Using dissipative particle dynamics (DPD) method, we simulated the temporal developments of equilibrium microstructures of nanotube dispersions with a bimodal length...
The modification of interface using nanoparticles in emulsions and immiscible polymer blends introduces elaborate methods to develop functional materials. In this study, we perform dissipative particle dynamics simulations to evaluate the distribution of interfacial tension over a polymer-polymer interface in the presence of carbon nanotubes (CNTs). The localization and interfacial self-assembly of...
In this work we study the rheology of polymeric brushes at the nanoscale interacting with an explicitly included atomic force microscopy (AFM) tip, using dissipative particle dynamics simulations, as models for pericellular brushes on epithelial cells. Two types of cells brushes are modeled: normal cells, whose surface is covered by brushes of uniform length, and cancer cells, which are covered by...
